NEW YORK CITY-As retailers continue to weave suburban concepts into the urban fabric, more brands—and big-boxes—are going vertical. But as the pendulum swings in favor of transit-oriented development, the nation’s top retailers agreed that the need for mass transportation is beginning to outweigh the need for traditional parking design, according to speakers during day two of the International Council of Shopping Centers’ 2011 New York National Conference & Deal Making event. The convention closed out at the Sheraton New York and Hilton New York Hotels on Tuesday afternoon, where total attendance exceeded 6,000 each day.
